Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To enable calculation of the reliability of a hypothesis corresponding to a change in a situation in respect to the hypothesis generated regarding target observation information, by calculating the frequency of fresh target observation from the target observation information in a correlation gate and the volume of the correlation gate. SOLUTION: A target motion data predicting unit 13 calculates a predictive error covariance estimating predictive values of the position and velocity at the present time of an already-controlled target and errors of the predictive values. A correlation gate volume calculator 14 calculates the volume of a correlation gate from the predictive error covariance and an observation error covariance. A fresh target observation frequency calculator 15 calculates a fresh target observation frequency showing the frequency of a fresh target being contained in a plurality of target observation information existing in the correlation gate, by using the target observation information in the correlation gate and the volume of the correlation gate.  Since the fresh target observation frequency at the time of occurrence of the fresh target can be known exactly according to this constitution, high reliability of a hypothesis can be obtained. A performance of correlation integration can be improved by reduction of the hypothesis by a hypothesis reducing unit 10 for which the reliability of the hypothesis is used.

Title: Ruled line copy processing system for document processor
Inventor: MAYUZUMI AKIRA
IPC: G06F17/21
Filed: 1987-10-28
Abstract: PURPOSE:To improve the document editing efficiency by discriminating the ruled line data from other data including the character data, etc., and copying only ruled lines. CONSTITUTION:The ruled line data is written directly into a copy receiver area 25 via a ruled line identifying part 32 and a blank processing part 33. While other data are defined as the blank data and written into the area 25. In other words, only the ruled line data and the blank data resist in the area 25. Therefore only the ruled lines are copied to a copy receiver 101 even though a copy transmitter 91 is equal to an area where the rules lines, characters, etc., are mixed together, i.e., the ruled line data and other data including the character data, etc., are mixed together in a copy transmitter area 22. Thus it is possible to select one of the copy processing of the ruled lines only, the shift processing, and the copy or shift processing of patterns and carries the selected processing with high efficiency.

Title: Controlling method for air conditioner
Inventor: KANAZAWA HIDETOSHI
IPC: F25B13/00
Filed: 1992-10-12
Abstract: PURPOSE:To cause a control of the valve travel of a refrigerant flow adjusting valve to be positively carried out before a compressor is restarted after protect ing operation and to enable the restarting of the compressor to be carried out smoothly. CONSTITUTION:In the case that a pressure of refrigerant is abnormally increased during operation, a compressor is stopped (ST1 to ST4). After stopping, if a predetermined time elapses, a compressor motor is restarted again and the restarting can be performed by three times (ST5 to ST8). Since as a cause for the abnormal operation in this case, it is frequently found that a refrigerant flow adjusting valve shows its clogged state or a hooking state, the refrigerant flow adjusting valve performs a resetting action before the compressor is restarted (ST11 to ST13). Then, the valve travel of the adjusting valve is set higher than that found in the case that the compressor is stopped and a load applied to the compressor is reduced.

Title: Signal processing system for photoelectric converter
Inventor: SHIMIZU TOSHIKAZU
IPC: H04N1/028
Filed: 1985-12-04
Abstract: PURPOSE:To reduce the variance of the gain of an amplifier circuit, to make the operating speed high and to lower power consumption of the circuit, by causing the output signal of the amplifier circuit to become an electric charge and electric charge-to-voltage converting the output of a photoelectric conversion processing circuit train by means of one signal processing circuit. CONSTITUTION:Photoelectric charges produced at a photoelectric converting element train 1a, 1b...1n are selected by scanning circuits, 2a, 2b...2n and amplified by amplifier circuits 3a, 3b...3n in electric charge. After the amplification the photoelectric charges are connected with an output line 5 by selection circuits 4a, 4b...4n. The signal charges outputted to the output line 5 are charge- to-voltage converted by a signal processing circuit 6 and outputted to a photoelectric conversion output terminal 7. Since the amplifier circuits 3a, 3b...3n are charge-electric charge amplifier circuits and the accuracy of their amplification factors is determined by the relative accuracy of their circuit constants, a high-accuracy amplification factor can easily be obtained even when the amplifier circuits 3a, 3b...3n are different from each other. Therefore, variance of the gains of the amplifier circuits due to variance in manufacture can sharply be reduced and high-speed operations and power consumption can be lowered.

Abstract: PURPOSE:To prevent the occurrence of a read error by reducing the pressing force of a feed roller immediately before the front end or the rear end of a recording medium run into or gets out of the feed roller during read when the recorded data of the recording medium is ready by a reading head while the medium being carried. CONSTITUTION:The recording medium 1 carried by a pair of the feed rollers 10 starts to be read by a reading means 4 at carrying speed, and when the front end of the recording medium 1 is detected soon by a second detecting means 13, a second retracting means 15 retracts either one of a pair of second feed rollers 11 toward a direction to part from the other for prescribed time. Accordingly, the front end of the recording medium 1 runs in between a pair of the second feed rollers 11 without changing its speed, and when the prescribed time elapses, retraction is canceled, and the feed roller is restored to a former state, and the recording medium 1 is interposed and held between a pair of the feed rollers 11 by prescribed pressure, and is carried by the first feed rollers 10 and the second feed rollers 11. Thus, jitter variation is reduced, and the occurrence of the read error can be prevented.

Abstract: PURPOSE: To provide an exposure base which can provide a uniform phase difference and uniform transmittance within its surface, an exposure mask, and a method for manufacturing the exposure base by adjusting the complex index of refraction the element composition ratio of a semitransparent film according to the thickness of the semitransparent film. CONSTITUTION: In an exposure base comprising a translucent base 41 on which is a semitransparent film 42 having the desired phase difference to the base 41 and the desired transmittance, the complex index of refraction or the element composition ratio of the semitransparent film 42 is adjusted to match the thickness of the semitransparent film 42. Adjustment of the complex index of refraction of the film is performed in such a way that during film formation a distribution of reactive gas in a film forming device is provided to correspond to the speed of film formation. Adjustment of the element composition ratio of the film is achieved by performing it during film formation in such a way as to correspond to the thickness of the film being formed.  Thus the complex index of refraction of the semitransparent film 42 is adjusted by adjustment of the composition ratio to correspond to a difference in thickness of the semitransparent film 42, so that a uniform phase difference and uniform intensity transmittance can be obtained within the surface of the base 41.
